Wikipedia
The prominence was named for William Lyon Mackenzie King (1874-1950), Canadian prime minister 1921-30 and 1935-48.
King was prime minister in 1927, during the celebration of the Diamond Jubilee of Confederation. One of the suggestions from the National Committee for the Celebration of the Diamond Jubilee of Confederation was to name mountains in the area now known as the Premier Range after prime ministers of Canada or Great Britain or premiers of British Columbia. In 1962, King garnered one of the peaks.
In mountaineering circles the mountain was known as “Hostility Mountain” since Munday’s description of his 1925 attempt. In 1963 the Canadian Alpine Club was informed by the director of the Geographical Branch that “Hostility Mountain” was now “Mount Mackenzie King.”
